The present invention provides a precursor solution and a modified membrane and a lithium battery comprising the same, the modified membrane is formed on two electrodes or an isolating membrane of the battery through a photopolymerization reaction or thermocuring precursor solution, the lithium battery having the modified membrane can effectively improve charge-discharge capability, cycle life and safety, and the modified membrane has excellent electrochemical performance. The modified film can be applied to a roll-to-roll process. And in the charge-discharge cycle process, the formation of lithium dendrites can be effectively inhibited or reduced, and the lithium ion battery has good cycle life and safety. The shuttle effect can be suppressed or mitigated in the form of a lithium-sulfur battery and a lithium-iodine battery. The above characteristics are beneficial for improving the product values of lithium ion batteries, lithium metal batteries, non-anode lithium batteries, lithium sulfur batteries and lithium iodine batteries.
